Specication forming part of Letters Patent No. 138,070, dated April 22,1873 application tiled February 8, 1873.

To all whom it may concern:

Be it known that I, GEORGE BRowNLEE, of Princeton, in the county ofGibson and State of Indiana, have invented a new and ImprovedSafety-Burner; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming a part of this specification, in which-Figure l is a vertical section of my safetyburner on the line c c, Fig.2. Fig. 2 is a top view of the same with dome and chimneycarrier takenofi". Fig. 3 is a detail vertical transverse section on line Fig. 2.Fig. et is a detail side view, partly in section, showing notches andrest for sliding lever. Fig. 5 is a horizontal section of the dome online y y, Fig. 1; and Fig. 6 is a vertical section of th dome, showingshape thereof.

Similar letters of reference indicate corresponding parts.

The object of my invention is to construct a burner for coal-oil lampsby the use of which explosions may be prevented, a quick extinguishmentofthe flame be obtained, and clearer and brighter light be produced. Myinvention consists in a weighted valve on the end of alever connectedwith a tubular wick-slide, Vwhich extinguishes the ilame either by thepressure of the oil-gases or at will by jerking the lamp or incliningthe same.

In the drawing, A represents the body of the lamp, with a handle, B. Tothe body A is applied in the usual manner the burner with wick-tube anddome. An aperture, b, in the bottom of the burner' leads to a secondbottom, d, with a corresponding aperture, into which is placed theextension c of an L-shaped weighted valve, Fig. 1. The leverarm of valveC rests on plate d, and is pivoted at s between the wick-tube and outercasing, so as to swing freely therein. An upward extension, g, of thearm of valve G forms with a movable lug, h, a small recess for spring D.The spring D is made of wire applied to the inside of the metalliccasing, and bent so as to pass through the recess between extension gand lug h. It then passes to the outside of the perforated casing E,which has notches t', between which said spring is moved up and down. Aprojection, K, at the lower notch, holds spring D therein until thelatter is displaced. The spring D is further attached to suitableprojections l of a tube, F, itted over the wick-tube, and sliding up anddown thereon. By a screw and nut, G, connected by a wire, m, to lever D,the action of the saine'is regulated at pleasure. A perforated plate, n,covers the valve and extinguisher mechanism, and allows a steady supplyof air to the tlame. The spring D is pressed down into the lower notch iunder the projection K, and the regulator m is so adjusted by nut G thatthe least pressure will disconnect spring I) from the lower notch andcarry the sliding tube Fover the wick-tube.

The oil-gases developed in body A, )ressing on extension e of weightedvalve G, will lift the same, and with it the pivoted end pin g, so thatspring D is released and tube F madeto slide upward over the wick,extinguishing the dame. The same effect will he produced by incliningthe body of the lamp or jerking the same.

By these means a great number of accidents, arising partly from impureoil or the careless handling of the lamp, may be altogether j avoided.

H is the chimney-plate with a series ofperforations, O, with outsideindentations i', slot p, and rounded projections q.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A weighted valve, G, having the extension e applied to an aperture inthe plate d over the body A, as and for the purpose described.

2. The lever-arm of valve C, having upward projection g and lug h,combined with the spring D and notch K of casing, as described,

to form a connection between valve G and sliding extinguisher F, as andfor the purpose set forth. j

3. The screw-regulator G m applied to the spring D, as and for thepurpose specified.
